In the device selected for illustrationpthe syringe comp-rises a foldingbag of rubber "of other plastic material carrying at its lower end aflexible tube; and it also comprises 'a' box or case which: in thisinstance is constructed of sheet meta-l, thebox being provided with ahinged top' lid or cover, a' body supporting the bag and ii'iithin'iwhich the foldedv bag can be disposed',- and a-hinged bottom or lowercover which in one poi sitfonrtansthe bag within they @dse and in an;other position per-mits the bag to-l-l'figf'down beil n drawings; thebox or case siiidic'itd generally vat ID', the body at Il; thehinged/top cover at (I2, the hinged bottomA at I3, the bigrt it;medesime tufbj at ls, and the bzzre'atand has a refl'tivelyjshauow uddi.'d. ierl metas@ minis particular' instante is; of sentiigreater'dimensiqnrmm,front to rear' than-rr nj das to sied as@ segamomes@ tee which m sans substantial use The ,be ser; allyof vuleaniz'drur and hasr'eentrant'side portions o'rlp-leats in ted at Manso that it' atendency@ y11e fiaty in condition in' which it, en 'be feesiefoiledigis; but werden of the bag is attached within the case body insuchua manner thatK the upper end is' heidenen; the, .rel't keine thatthe besvfhen me-Wr and in the pendent position; assumes the shape shownihtheiraWhgSi The bag is` ansehe@ t5 andvsupprtd fidf vthe eriSf,,reselrods fsthe'dnl e ti' near' the upper edge of the latter lami-,nthegfront and rear(walls" of the body, as sh n Fie: 41 The flnt rod ifs.indicatdfetgl? :arid f @from s. .Een bf me@ attaching rises'a'svshown inEfigkQa rod bodyfl and ori sleeve' 2n of rubber @other su@ e niaterlalSvrrsenine the, fdd bey- The sleeve 4@tPxe f1 1s ses the spapbe'tweenthe site walls 2'! of the case body. The ends ofthe b 'odj ies IS areVprovided `with flaredhollow or recessed iort'is so that the end portionsof the rods can b'ebent to forrn an'ge'd clinching heads 22 by whichthe' rods are secured iii place, as' shown; feln example, in Fig. y5. Atthe topf of the bag' the sheetA rubber material is turned up'n itself toprovide a part 22a like a hem at the sides and ert'isI of the bag, whichis provided at each end Witha through opening E3 in' which thecorrespondng rod body and its associated sleeve are closely tted: In"this manner the bag at its front' and rear edges at the mouth thereof isse-l cr'ely Amounted uponv the respective attaching rods.

At the forward edge of the bag mouth the at; taching rod l1 has the endportions of its body extending through perforations in the side walls ofthe'case body, and the rod body is clinched against' the' outer faces ofsaid side walls. lin the ose' of thel -rod |18,however, the rod isutilized in providing a hinge between the lid I2 and the case body. Forthis purpose the lid I2 is provided with downturned side flanges 24which adjacent the rear end of the lid are extended to provide hingelugs 25 positioned outside of and against the side walls of the casebody, and these lugs are provided with perforations registering withperforations in the side walls, and the rod body I9 extends throughthese perforations and is clinched against the outer faces of the lugs25 in a manner such that the rod body le is rigid with the lid andswings with the lid when the lid is opened and closed.

Preferably the upper edge of the case body is turned inwardly on agradual curve, as shown at 26, along the sides and ends of the oase bodyso as to overhang the mouth of the bag to a certain extent and therebyinhibit the spilling or leakage of liquid being poured into the bag.

The lower cover or bottom I3 is provided with side flanges Z'l and withhinging lugs 28 corresponding to parts previously described, and thelugs 28 are outside of and against the side walls of the case body andare hinged by means of short rivet members 29 extending throughregistering perforations in the hinge lugs and the side walls.

Each of the covers I2 and I3 is provided with a flange 30 at the forwardedge and a flange 3l at the rear edge of the same depth as the flanges2d and 21 except for a fastening portion 22 hereinafter mentioned. Thehinge lugs 25 and 28 project laterally beyond the flanges 3i, and whenthe covers reach the positions shown in Figs. 2 and 4, in which they arevertically disposed, the

flanges 3| have their edges come into engagement with the rear wall ofthe case body through the length of said wall so as to provide stops.These stops come into action when the cover is swung into a position inwhich it is at right angles to the body.

The fastening portion 32 of the lid flange, mentioned above, is ofsomewhat greater depth than the remainder of the flange and isdownwardly sloped toward a point at the lower edge, and is provided witha lower tip 33 adapted to contact and ride over a small rivet 34 appliedto the front wall of the case body, and there is a frictional interlockbetween the head of the rivet 34 and a surface of a cup-like recess 35at the inner part of the fastening portion 32. By this construction aneffective snap fastening is provided between the cover and the box bodywhich will hold the cover in the closed position in an effective manner,although permitting convenient opening of the cover when that isdesired.

The upper lid I2 is provided with a suitable opening or aperture 36 tobe engaged by a nail or hook on the supporting wall, and in use thedevice has the position shown in Figs. 1 and 2. When in this position,the bag can be lled with a liquid and used in the customary manner. Itis important to note that in this position of the parts the case body isstrongly braced by the engagement therewith of the upper and lower lidsin the manner described above. Therefore, the case body, when the bag isfilled with liquid, will not be displaced so as to take a position inwhich liquid will be spilled out of the bag. After use and removal ofliquid from the bag, the device can be readily folded to place it incondition for transport or storage, in which condition the case containsthe operative parts and has the appearance shown in Fig. 6, the bagbeing folded within the case, and the tube together with the pipe I5and/or other appliances being stored in the case under the folded bag.Before folding the bag, the pipe is removed from the tube, the bagfolded at the lower part so as to be stored within the lower part of thecase body, and the tube disposed in the bottom of the case body in aconvenient manner.

The mouth portion of theibag is of such dimensions that along the sidesand ends it is overhung, at least in part, by the inturned edge at theupper part of the case body, and the cross rods are set into the casebody so as to be very closely adjacent the front and rear walls of thelatter, the result of this arrangement being that the leakage of liquidover the upper edges of the bag, and between the bag and the walls ofthe case body, is inhibited. The cross rods are permanently connected tothe case body, and thereby the bag is permanently connected to it sothat there is no difficulty occasioned by the misplacement or loss ofthe bag element, which is at all times ready for use. The bag mouth llsthe case body near the upper edge of the latter, so as to extendsubstantially from side to side and from end to end. The case body, withits enclosed bag, is strongly supported from the supporting wall throughthe media of the upper and lower covers in a position in which the casebody extends at right angles to the wall.

The construction used for hinging the upper lid is of the most simpleand effective kind, the rear cross rod serving as a part of the hinge,thereby reducing to a minimum the number of separate parts used in theassemblage. The hinging axis is near the upper edge of the case body andclose to the rear wall of the case body, but within this wall, and iscoincident with the axis of the adjacent cross rod.

While the enclosing case for the article is shown A as constructed ofmetal, other materials, such as plastic material, may be used for thispurpose. In any event, the case is preferably relatively rigid so as toserve as a protection for the contents. The case not only protects thesyringe parts, but serves to prevent clothing and the like from cominginto contact with moisture remaining on the syringe parts after use.

Various modifications and changes in the details can be made withoutdeparting from the principles of the invention or the scope of theclaims.
